“As the social media landscape ebbs and flows, the team at BBC Research & Development are researching social technologies and exploring possibilities for the BBC. One part of our work is to establish a BBC presence in the distributed collection of social networks known as the Fediverse, a collection of social media applications all linked together by common protocols. The most common software used in this area is Mastodon, a Twitter-like social networking service with around 2 million active monthly users. We are now running an experimental BBC Mastodon server at https://social.bbc where you can follow some of the BBC’s social media accounts, including BBC R&D, Radio 4 and 5 Live. We hope to be able to add more accounts from other areas of the BBC at some point.”
Maybe, but we aren’t at the critical mass where downvotes posts and comments are routinely hidden. People will see downvoted content and interact with it.
You are also missing that the other site used karma as a way to judge if an account should be allowed to talk more. I had enough karma there so that I stopped getting the “you’re commenting too much” pause when commenting a lot. Some subs also used minimum karma points as a way to judge if someone was a troll or not. That doesn’t exist here.
